Corgan's voice is somewhat of an "acquried taste" for most fans. I can easily see why some folks don't like SP.
I, for one, love them. Their music was some of the best that came out of the 90's.
I caught them in Athens early this year. It was the first time I've ever seen them. Blew my mind away. They played lots of old stuff, which was great because I'm not too fond of the new album.
James and D'arcy were missed though...
Jimmy Chamberline was a beast. That guy is still easily one of the best drummers in rock today.
